Purpose

The data provides an overview of the seabed sedimentation environment in the area that has been mapped. Areas with deposition of fine-grained sediments (clay / silt) indicate weak bottom currents and a calm depositional environment, while coarse-grained sediments indicate currents that prevent deposition of or wash away fine-grained sediments, while the coarser (sand, gravel and rock) remain. The map thus gives a clue to the strength and direction of the bottom currents.

Specific usage

The data of this dataset series can be used as basis for areal planning, environmental planning, habitat mapping, vulnerability analyzes, impact analysis in connection with installations on the seabed, location of aquaculture farms etc. The sedimentary environment map provides an indication of the velocity (strength) and direction of the bottom currents and how they influence the seabed .

Statement

The two datasets of the dataset series Sedimentary environment are interpreted and digitized by NGU. Source data for interpretations are from the Geological Survey of Norway (NGU), the Norwegian Mapping Authority, the Institute of Marine Research (HI) and the Norwegian Defence Research Establishment (FFI). Sedimentary environment is interpreted based on maps of Seabed sediments (grain size) and detailed baymetry data. Sedimentary environment is digitized and prepared using ArcGIS tools. The methodology is described in the ‘Målemetode’ and ‘GeolPavisningstype’ fields. The datasets are stored in separate feature classes in NGU's marine geological database and are made available for download separately.
